The LG KF757, also known as LG Secret, was a notable mobile phone launched in 2008. While it may seem outdated by today's smartphone standards, the device was well-regarded for its sleek design and functionality during its release. It was part of LG's effort to compete in the feature phone market with its balance of design, multimedia, and connectivity features.
The LG KF757 Secret boasted an elegant design with dimensions of 102.8 x 50.8 x 11.8 mm and a weight of 116 grams. Its slim and lightweight build made it a portable device. The phone's body was crafted with high-quality materials, featuring scratch-resistant glass which added to its durability. The device was available in three colors: Black, Ruby Violet, and Titan Gold, catering to different style preferences.
The device featured a 2.4-inch TFT resistive touchscreen with support for 256K colors, which was standard for phones of that era. The screen resolution stood at 240 x 320 pixels with a pixel density of around 167 ppi, providing clear and vibrant visuals appropriate for its time. While not on par with today's high-resolution displays, it was sufficient for basic multimedia consumption and navigation.
One of the standout features of the LG Secret was its camera. Equipped with a 5-megapixel sensor and autofocus capability, it was considered advanced for feature phones. An LED flash complemented the camera, enhancing photo quality in low-light conditions. The device supported video recording at 480p@30fps and 320p@120fps, providing users the capability to capture moving images as well.
In terms of connectivity, the LG Secret supported GSM and HSPA networks, with 2G bands at frequencies of GSM 900/1800/1900 and 3G HSDPA 2100. It offered speeds up to HSPA 3.6/0.384 Mbps, allowing decent internet browsing. Additional connectivity features included Bluetooth 2.0 with A2DP for wireless audio and Wi-Fi 802.11 b/g for internet access.
The phone supported a variety of multimedia functionalities, including a stereo FM radio with RDS. Although lacking a 3.5mm jack, it incorporated a loudspeaker for hands-free use. The multimedia experience was further enriched by Java support (MIDP 2.0), providing users access to downloadable games, some of which were motion-based, taking advantage of the device’s accelerometer sensor.
Internally, the LG Secret provided 100MB of storage, which at the time was modest but manageable for basic phone functions. For users requiring additional space, the presence of a dedicated microSDHC card slot allowed for memory expansion, useful for storing more music, photos, and applications. The phone could store up to 1000 phonebook entries and keep records for 40 dialed, received, and missed calls.
The device was powered by a removable Li-Ion 800 mAh battery. While the capacity might seem low today, it was adequate for a feature phone, offering up to 220 hours of standby time and approximately 3 hours and 30 minutes of talk time, depending on usage patterns.
The LG Secret operated as a feature phone with a user-friendly interface. Its software included messaging options such as SMS, EMS, MMS, and Email. The phone supported WAP 2.0/xHTML and HTML for internet browsing. While it did not support positioning technologies like GPS, it came equipped with an accelerometer to enhance its gaming capabilities.
At its core, the LG KF757 Secret was a remarkable device in its time, combining advanced multimedia capabilities with a stylish design. Its focus on a quality camera, connectivity options, and expandable memory appealed to tech-savvy users in the late 2000s. Despite being discontinued, the device remains a notable example of the advancements in feature phones during that period.
